20080273048 | LIQUID CONTAINER - The invention provides a liquid container for storing liquid to be supplied to a liquid consuming apparatus. The liquid container is constructed such that pressurized fluid is sent to its inside so that the liquid in the inside is delivered to the outside. The liquid container includes a container body which stores the liquid in its inside. The container body includes a pressurized fluid introduction port for introducing the pressurized fluid to the inside and a liquid delivery port for delivering the liquid to the outside. A detection unit is provided in the container body and outputs an output signal which is changed in accordance with a change in pressure of the liquid in the inside of the container body. | 11-06-2008 |
20080303883 | INK-JET RECORDING DEVICE AND INK SUPPLY UNIT SUITABLE FOR IT - Ink maintained at a negative pressure state is supplied to an ink-jet recording head via an ink supply mechanism constructed as a differential pressure valve having a coil spring and a movable membrane normally contacted elastically with a valve seat by the coil spring. | 12-11-2008 |
20080316287 | INK CARTRIDGE AND METHOD OF REGULATING FLUID FLOW - In an ink cartridge, a negative pressure generating mechanism is disposed between an ink storage region and an ink supply port, and has a wall surface having two through-holes for ink flow, and a valve member contacted with and separated from the through-hole by receiving a pressure in an ink supply port side. Ink flowing via the through-hole is supplied via the through-hole to the ink supply port. | 12-25-2008 |
20090167827 | INK CARTRIDGE FOR INK JET RECORDING APPARATUS, CONNECTION UNIT AND INK JET RECORDING APPARATUS - An ink cartridge for supplying the ink in an ink reserving chamber via an ink supply port into a recording head has a differential pressure valve mechanism disposed between an ink flow port and the ink supply port in the ink reserving chamber, whereby the ink is supplied an adequate amount to the recording head by opening or closing the differential pressure valve mechanism in accordance with an ink pressure of the recording head. As a result, it is possible to supply the ink at a substantially constant pressure to the recording head without regard to the variation in the amount of ink or the-movement of the carriage. | 07-02-2009 |
20120062663 | INK CARTRIDGE FOR INK JET RECORDING APPARATUS, CONNECTION UNIT AND INK JET RECORDING APPARATUS - An ink cartridge for supplying the ink in an ink reserving chamber via an ink supply port into a recording head has a differential pressure valve mechanism disposed between an ink flow port and the ink supply port in the ink reserving chamber, whereby the ink is supplied an adequate amount to the recording head by opening or closing the differential pressure valve mechanism in accordance with an ink pressure of the recording head. As a result, it is possible to supply the ink at a substantially constant pressure to the recording head without regard to the variation in the amount of ink or the movement of the carriage. | 03-15-2012 |
